I installed ubuntu-desktop, kubuntu-desktop and xubuntu-desktop on my Lubuntu.

I wanted to remove them and found this. I first used the command to remove ubuntu-desktop. While running it, I noticed that it was also deleting KDE packages.

The command took a while and I had to go away, so I locked the screen (And it used the lock screen from ubuntu-desktop). After 2 hours I came back and pressed a button to wake from standby. After that it reacted to NOTHING so I had to do a forced shutdown.

And now it won't start anymore (black screen). I can still get into Windows and safemode. I tried safemode, enabling network and running apt-get install lubuntu-desktop, but it looks like it already is there. I tried dpkg and apt-get autoremove and doing apt-get install lubuntu-desktop again, but it still looks like it already is there. When I reboot now I do get the Lubuntu logo but after that, black screen again.

I also tried removing lubuntu-desktop and installing it again but that didn't help either.
